I wasn't really going for power, but what you're saying goes inline with other comments - put more body behind my punches. Great idea on pushing the bag to simulate moving target. Good feedback, thanks.:good
You're welcome. Keep punching. Also, work on slipping imaginary punches, then countering on the heavy bag while moving youre feet. This will help iron out your footwork. Most newbies do not understand they need their feet set to throw good punches.
